Research laboratory for grid integration of distributed renewable energy resources - design and realization -

摘要: The growing amount of electric energy generated from distributed resources (DER), mainly renewables, requires their appropriate integration into the electrical grid. These renewable power sources are feeding-in via converters and can be controlled well. Investigation grid means investigating control hardware concept in dedicated environment. Measurements at downscaled systems a laboratory environment time- cost-efficient way to investigate this. properties grid, voltage amplitude, frequency phase as well impedance vary substantially by time, moreover is dependent. have emulated for measurements integration. A research test-bench has been developed. comprises special developed emulation, sag generation, correction analysis. Here, design realization these investigations on presented. Representative each system prove functionality.
